>Description:
	The mouse port of a MCT PS/2-USB adapter is not always
	detected.  Replugging the adapter would fix the problem but
	unfortunately at the moment this triggers usb/95348.

	Dmesg on my system, when the mouse doesn't work, shows:

	[...]
	ukbd0: MCT Corp. PS/2 - USB Interface Adaptor, rev 1.10/1.00, addr 2, iclass 3/1
	kbd1 at ukbd0
	uhid0: MCT Corp. PS/2 - USB Interface Adaptor, rev 1.10/1.00, addr 2, iclass 3/1
	[...]

	Replugging the adapter:

	ukbd0: at uhub0 port 1 (addr 2) disconnected
	ukbd0: detached
	uhid0: at uhub0 port 1 (addr 2) disconnected
	uhid0: detached
	ukbd0: MCT Corp. PS/2 - USB Interface Adaptor, rev 1.10/1.00, addr 2, iclass 3/1
	kbd1 at ukbd0
	ums0: MCT Corp. PS/2 - USB Interface Adaptor, rev 1.10/1.00, addr 2, iclass 3/1
	ums0: 3 buttons and Z dir.

>How-To-Repeat:
	Boot with an MCT PS/2 adaptor connected to the USB port.  Move
	the mouse; the pointer should stay still.  If the pointer
	moves, it was a lucky start: reboot.
>Fix:

	No one known.
	Replugging the adapter is a workaround.
